From Apple’s AirPlay webpage:

Leading TV manufacturers are integrating AirPlay 2 directly into their TVs, so now you can effortlessly share or mirror almost anything from your iOS device or Mac directly to your AirPlay 2–enabled smart TV. You can even play music on the TV and sync it with other AirPlay 2–compatible speakers anywhere in your home.

Samsung was the first to announce support for AirPlay 2 alongside the ability to stream iTunes movies and TV shows on their smart TVs, but I expect we’ll be seeing more television manufacturers announcing support soon too.
